CONNECTION-BOX.

Specification of Letters Patent.

Patented May 5, 1908.

To all whom it may concern:

Be it known that I, RUSSELL Donn Hora- BIRD, a citizen. of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented con tain new and useful Improvements in (ionnection-Boxes, of which the following is a specification. 1

My invention relates to outlet or connection-boxes for interior electric wiring, and more particularly to connection boxes or switch boxes usually termed multiple unit or munit boxes; and my object is to provide a single unit box so constructed and having such accessories. that a plurality of such units may be readily ganged or built up by the workman into boxes of any desired size, at the point of installation, and without the use of any special tools. i attain these objects by the construction shown in the accompanying drawing, in which:

Figure 1 is a side elevation of a single box or unit; Fig 2 a top plan view of the same; Fig. 3 a side elevation of several units built up into a multiple unit box; Fig. 4- is an end elevation of a unit with a slightly modified form of lug, and Fig. 5 is a top plan of a further modification, showing the manner of gangng the same.

1 represents the ends ol the box, preii orably stamped and die-shaped from sheet metal of suitable thickness. These ends are identical in all respects, and intcrchangcablc.

2 represents the body of the. box, comprising the bottom and two integral sides, also preferably stamped and bent u) from suitable plate or sheet metal and, h c the ends, intcrchangeablc. The ends are provided with suitably tapped lugs 25, symmetrically located, and the sides with perforations 4, correspondingly located, so that the sides and ends may be assembled and secured by screws The lugs 3 may be turned to fit either the exterior of the box, as in Fig. 4, or the interior; but preferably the latter, because of the neuter appearance of the assembled box and the saving of stock occasioned thereby. The box-body is also provided with lugs (j and screws 7 for supporting the incloscd switch, or other litting, (not shown). Both ends and body are provided with numerous, roarlily-removable disks 8, closely hitting the. holes from which they are punched, ant permitting the connecting up of wires at any desired pointj 12, for ease oi adjustment. instead of providing separate clips, one end of each unit may be furnished with a longer supporting lug 13 (Fig. 5), secured by two screws; while the opposite end has two shorter or single lugs.

Considering Figs. 1, 2 and l, it will be readily seen that each unit is complete in itself, and is also furnished with all necessary fittings to enable it .to be assembled with others into a box of any desired size, with the use o'l no other tool than a screw-driver. For example; in Fig. 3, both ends of each of three units and one end of each of two units are removed, and. live interchangeable bodies and two ends united by the clips 11 into a 30 box suitable for a bank of live switches. In such caso, o! so many lugs 9 need be. retaincd us are nm-cssary to properly support the box in place; and these lugs may be adusted or reversed as may be necessary to 35 proocrly seat the. cover-plate flush ou the dull stlll'arc. in Fig. 5, one end of each cl two boxes is removed and the lugs of the boxes rearranged with one long lug 13 at each side .oi' the multiple unit, to be used as a combined clip and lug; While the single lugs may be removed or located as may be. desirable.

()thcr modifications than those described may be made without departing from my iuveni 'oh; since hat i claim is:

l. A connection box for electric wiring, comprising a body section and interchangeable and sections, said sections havin co6p- 0 crating connecting means, and ad itional means for connecting a plurality of body sections to form a larger sectional box.

2. A connection box for electric Wiring,

(mm'prising a body section and interchangeable end sections, said body section having rcadily-rcmovable, cooperating means for connecting a plurality of body sections and end sections to form a multiple unit box of any desired size. 1
